Mistress Sidonia has suspended her bondage slave in the outdoor dungeon, tied tightly and held securely by the straitjacket. She teases his nipples and cock before stretching his asshole with her fingers, placing the fucking machine in place. The big dildo is pointed upwards and as she uses the remote control to start thrusting and penetrating his tight hole, speeding up and hitting his prostate over and over, left hanging and fucked until she is satisfied.
